For the past few months, KatFennec and I have been working on a 100% custom site called EvoCrit (https://evocrit.com) which features my adoptable projects, allows for posting images, and is planned to have plenty of HTML5 content including interactive mini games and adoptable creation tools.

This project is intended to be somewhat of a hybrid of traditional adoptable/virtual pet sites and the adoptables found on sites like DeviantArt, and is still in development. Screenshots are located here.

A lot has been done on EvoCrit, and it has temporarily moved, but the new URL still uses the same database. Feel free to make an account, there's a guide for getting started here.
More updates to come.
